Running two 8 ohms cabs on my Tc-50

Post by jf.quevillon » Sun May 26, 2019 6:46 pm

I'm new to this forum and was wondering if any of you have experience with a setup of two 2x12 cab plugged in parralel on a TC-50?

Previously I had a 2x12, in 8 ohms and it sounded pretty lound but I was missing the presence of 4 speakers so O decided to ordered a second one (also in 8ohms)

I just recived it and when plugging the two together, I was surprised on how much less volume I got. I now need, to push the amp master at around 3, 4 o'clock (yeah I know I play loud..) with all my channel volume pretty high already (4,5 o'clock).

I reed that I had to switch the 4ohms since I have two in parallel now. Am I doing something wrong.

I'm considering the TC-100 if I dont have enough power..

What do you guys think?

Two cabs, each 8 ohms, and each plugged into the back of the amp requires that you set the switch to 4 ohms. That is correct. In fact, if you do not run with the switch at 4 ohms with two 8 ohm cabs hooked directly into the amp you could damage the amp.

Not sure why you have a volume drop with that? Have you tried each cab hooked up to the amp one at a time (with 8 ohm switch setting) to see if there is a volume difference?

The TC-100 does have more power and oomph, but in real sound pressure terms you'll have about 3 more dB, which isn't like twice as loud or anything. But, you are pushing the amp pretty hard as it is, so the 100W version could be what you are looking for. Nonetheless, the TC-50 should not be less loud with two cabs.
